Question

Ram can do a piece of work in 6 days and Shyam can finish the same work in 12 days. How much work will be finished if both work together for 2 days?

• A. One-fourth of the work
• B. One-third of the work
• C. Half of the work
• D. Whole of the work

Answer 1

Answer: (C)

Half of the work

Ram's 1 day's work $=\frac{1}{6}$
Shyam's 1 day's work $=\frac{1}{12}$
The part of work in 2 day's by both $=2\left(\frac{1}{6}+\frac{1}{12}\right)=2\left(\frac{2+1}{12}\right)=2\times \frac{3}{12}=\frac{1}{2}$
